Utilization of banana and cassava peel as local microorganism materials in household organic waste composting by takakura method

Abstract

This research compares household organic waste compost results with the addition of local microorganism activators from banana peel and cassava peel waste with Effective Microorganisms (EM4). The composting method used is aerobic composting with the Takakura composting technique. This composting is carried out in 5 variations consisting of variation 1 (50% organic waste: 50% finished compost), variation 2 (50% organic waste: 50% finished compost: EM4), variation 3 (50% organic waste: 50% finished compost: local microorganism banana peel), variation 4 (50% organic waste: 50% compost made: local microorganism cassava peel), variation 5 (50% organic waste: 50% finished compost: local microorganism banana peel and cassava peel). The results showed that all variations of composting had met the maturity standard for parameters of temperature, pH, material reduction, texture, color, and smell and had met the SNI 19-7030-2004 standards. Analysis of all compost quality, including C-organic, nitrogen, C / N ratio, phosphorus, and potassium, has met SNI 19-7030-2004 standards. From 4 kg of raw material produced, solid compost ranges at 2.7-3 kg. The use of activators in the composting process can speed up the composting time by 8-12 days. Compost variations by scoring results in the compost consisting of 50% organic waste and 50% finished compost with 5 ml of local microorganism activator banana peel, and cassava peel is the best variation in compost maturity quality.
